PUMP-CYLINDER PROTECTOR.

To ali fio/wm t may conce/m.'

Be it known that Gos lVrnsn, a citizen of the United States ot' America,residing at New Hartford, in the county ot' Butler and State of iowa,has invented new and useful Improvements in Pump-Cylinder Protectors, ofwhich the 'following is a specification.

The continual working in the cylinder ot' a well pump often results inthe loosening ot the lower cap and the attached pipe, permitting thelatter to drop into the well and incurring the expense and trouble o'fishing it out. The purpose of the invention, therefore, is to provide adevice for connection with the pump cylinder to positively prevent theunscrewing ot' the cap either at the upper or lower end oi" the same andat least prevent the dropping ot any loosened parts should a cap Jforany reason become unscrewed.

lVith this purpose in view, the invention consists in a construction andcombination of parts of which a preferred embodiment is illustrated inthe accompanying drawings, wherein Figure l is a side elevational viewshowing a pump cylinder and portions oi.i the connecting pipes at thcupper and lower it" ends, the ndevice being` shown in operative positionthereon.

Figure 2 a longitiulimll sectional view on the line 2-2 ot l ".igure l.

Figure 3 is a transverse sectional view V on the line 23H3 of Figure 1l.

The invention consists oif complemental yoke members l and 2` madepreferably of thin metal cut or stamped to provide the side arms S andthe heads Jr, the latter being of greater width than the side arms andbeing provided with openings 5 lor engagement with the wrench seats 6 ofthe caps 7 of a pump cylinder' 8. The arms of one of the members areprovided with slots 9 while the arms of the other member have `holesthrough which the bolts 10 project, these bolts also extending throughthe slots 9 to permit adjustment of the members toward and away fromeach other, which "0 arrangement provides for the adjustment of thedevice as to length to bring the heads @i into engagement with the capsof different length cylinders within a specific range.

lVith the one member engaging the upper cap and the other memberengaging the lower cap and both caps generally being connected by thesame kind of threads, that is, right hand or left hand. whichever 'isused, it is obvious that any tendency of the one cap to unscrew willresult, by virtue ot the device, in tending to cause the other cap toscrew up. Thus either cap is held in position on the barrel. Should thedevice, however, be carelessly adjusted as to length so that the lowerhead may be disengaged from the lower cap and the latter' for any reasonbecome unscrewed, the device will serve a means to catch the cap and thedepending section ot pipe and thus prevent its dropping into the well,thereby avoid- F ing the necessity of having to fish it out.

The invention having been described, what is claimed as new and usefulis:

l. A device for the purpose indicated comprising complement-al membersprovided with cylinder cap engaging heads and parallel arms, and meansYtor connecting the arms together at their terminals.

2. A device torthe purpose indicated comprising com plemental membersprovided with cylinder cap engaging heads and parallel arms, andadjustable means lor connect ing the arms tog ther at their terminals toprovide for variations in the length of `the device as a whole toaccommodate different lengths of pump cylinders.

3. A device for the purpose indicated comprising complemental membersprovided with cylinder cap engaging heads and parallel arms, andadjustable means lor connecting the arms together at their terminals toprovide for variations in the length ot the device as a whole toaccommodate diierent lengths of-pump cylinders, said means comprisingslots in the arms of one ofthe n1enibers and bolts carried by the armsof the other member and projecting through the slots of the first saidmember. y

In testimony whereof he aixeshis signature.
